Effects of comb age on honey bee colony growth and brood survivorship

Abstract

SUMMARYThis research examined the effects of comb age on honey bee colony growth and brood survivorship. Experimental old combs were of an unknown age, but were dark and heavy as typical of combs one or more years old. New combs were produced just prior to the beginning of the experiment and had never had brood previously reared in them. Either old or new combs were installed into each of 21–24 nucleus colonies each year over a three-year period. On average, colonies with new comb produced a greater area (cm2) of brood, a greater area (cm2) of sealed brood, and a higher weight of individual young bees (mg). Brood survivorship was the only variable significantly higher in old comb.
